Generally peaking, required files when made available come in 2 varieties.
One, you already have it or it’s free content, you just have to find it in your vault.
2, a redeem code is made available for you to get the thing from the launcher.
the links can be a bit hidden, but generally in the course master page (the one with your progress and the topics) you have tabs at the top. One of these tabs will provide the code to activate the files.
from then on, if like me you have a library/voult of 80 or so items, it’s really hard to find the content you just redeemed.
curiously enough, this information is detailed I think in the videos made by Wadstein. The same guy that makes all the WTF and WTF is for UE4 stuff…
It was also mentioned in a step by step fashion for the Post Process materials tutorial.
Some other courses simply don’t have any required files…
